OK, bare with me here, the legend is now all over the map alphabetically. If I do another revision I might run out of letters, LOL.
Version 4 Legend
A - 3/4" PVC over-top return manifold
B - Strainer overflow w/ 1" drilled bulkhead
C - 1" PVC drain pipe
D - 3/4" PVC return pipe
E - 1" PVC drain pipe @ 90 degree angle
F - Refuge return chamber
G - 10-gallon refuge
H - DIY stand (to hold refuge above sump)
I - 1" bulkhead w/ hose attachment
J - Refuge main overflow drain tube
K - Drain area with filter bag
L - 20-gallon Sump
M - Baffles, first at 1.5" and the next at 1"
N - Eheim 1262 return pump
O - Refuge Light
Q - 1/2" PVC refuge feed
U - 90 degree PVC elbows that swivel
V - 1/2" gate valve (teed off return pipe)
W - Back-up refuge overflow output tube
X - AquaC EV-180 protein skimmer
Y - 1" gate valve
Changes... X, U, V, W, and Y have been added.
M, the baffles, has the first baffle 1.5" apart instead of 1" like the rest, to allow more opportunity for bubbles to escape.
E, is now at a 90 degree angle, to allow for U, a 90 degree joint that brings the pipe into the stand area and to another swivelling attachment. Tell me if you like the drain going directly to the refuge better.
K has now be altered. The glass separation has been removed to provide more room for the protein skimmer, and a filter sock was added to the drain
F, the refuge return chamber, is now smaller, as it doesn’t need to be so large. In fact, it might not need to be there at all.
W has been added in case J gets plugged. I won't bother putting that in the baffles because it's ever needed, pods are the least of my concern.
V and Y are gate valves instead of ball valves to allow greater flow control.
Q is now fed from the return instead of having a separate pump
Also, the return pump area in the sump has been enlarged considerably.
